I think you are talking about several different things here. 1st, DOMS is not indicative, necessarily, of muscle stimulation or growth.
I personally think that deadlifts are great for back, leg, and core development, but your mileage may vary. And from a bodybuilding perspective, being a bit fatigued from DLs prior to squatting is not necessarily a bad thing. From a pure strength training perspective it may be (but notice, you are in the bodybuilding section).
What is your routine? What is your current weight and physique, how much are you lifting, etc? It is really hard to offer advice on what to do or not to do without having a better picture of what you are currently doing and how you are doing it.
